python基础（二）——类与方法

class human(object):    #定义一个父类
    def __init__(self, name):
        self.__name = name
        self.__walk = True
    def get_name(self):

        if self.__walk == True:
            print("human walks")
        else:
            print("human not walks")
    def set_walk(self, walk):
        self.__walk = walk
class man(human):   #定义一个子类，继承human类
    def __init__(self, name, has_wife):
        super(man, self).__init__(name)
        self.__has_wife = has_wife
    def marry(self):
        if self.__has_wife == "y":
            print("married")
        else:
            print("not yet")
    def smoke(self):
        print("man smoke")
    def drink(self):
        print("man drink")
class woman(human):     #定义一个子类，继承human类
    def __init__(self, name, has_husband):
        super(woman, self).__init__(name)
